1 Executive Summary Iluka Resources Limited (Iluka) operates the Pit 23 by-products disposal facility located at the Douglas Mine in the Kanagulk area and within the municipality of the Horsham Rural City. Pursuant to Planning Permit 15-105 issued by Horsham Rural City Council (HRCC), and the subsidiary Pit 23 Incoming Waste Monitoring Plan (IWMP), the Pit 23 facility is approved for the disposal of mineral separation by-products and used dust filter bags from the Iluka Hamilton Mineral Separation (MSP) which contain or are contaminated with Naturally Occurring Radioactive Material (NORM), and concrete and steel which contains or is contaminated with NORM associated with plant and infrastructure from nominated Iluka sites within Victoria.

Complementing the IWMP are the endorsed Pit 23 Environmental Management Plan (EMP) which addresses the identification, management and monitoring of environmental risks associated with the approved development and use; and the endorsed Rehabilitation and Vegetation Management Plan (R&VMP) which addresses the future rehabilitation of the Pit 23 facility including infrastructure decommissioning, landform reinstatement and end land use. This report is submitted in accordance with Section 12.2 of the endorsed Iluka Pit 23 EMP and outlines the results of monitoring and management actions undertaken during the period 1st January 2020 to 30th June 2020. Key commentary on environmental monitoring outcomes and performance against compliance objectives in the Pit EMP for the H1 2020 reporting period:

• There were no exceedances of applicable limits for radionuclides or any other analytes in groundwater in bores down-gradient of Pit 23 attributable to disposal activities;

• There were no surface water discharges from the Pit 23 disturbance area;

• There were no exceedances of applicable limits for radionuclides or any other analytes in groundwater-fed surface water sites down-gradient of Pit 23 attributable to disposal activities;

• No noise complaints were received;

• There were no exceedances of the PM10 limit attributable to Pit 23 operations; • There were no exceedances of the air concentration limits for radon or thoron;

• Measured concentrations of gross alpha radiation in airborne dust were within the range of historical values; and

• Updated groundwater level contours and flow-paths show no material change from the hydrogeological model contours developed in 2015 by CDM Smith.

Detailed assessment of compliance, key results and management actions are provided in Section 4 and 5 of the enclosed report.

2 Introduction Iluka Resources Limited (Iluka) operates the Pit 23 by-products disposal facility located at the Douglas Mine in the Kanagulk area and within the municipality of the Horsham Rural City (Figure 1 and Figure 2).

Pursuant to Planning Permit 15-105 issued by Horsham Rural City Council (HRCC), and the subsidiary Pit 23 Incoming Waste Monitoring Plan (IWMP), the Pit 23 facility is approved for the disposal of mineral separation by-products and used dust filter bags from the Iluka Hamilton Mineral Separation (MSP) which contain or are contaminated with Naturally Occurring Radioactive Material (NORM), and concrete and steel which contains or is contaminated with NORM associated with plant and infrastructure from nominated Iluka sites within Victoria.

2.1 Planning Permit 15-105

Under the Horsham Planning Scheme the subject land is in the Farming Zone and under the provisions of that zone a permit is required for use and development for Industry (Refuse Disposal). On 25th February 2017 Planning Permit 15-105, (the Permit) was issued by the Horsham Rural City Council as the Responsible Authority to allow:

Use and development of the land for the disposal of waste by-products associated with or sourced through mineral sands processing undertaken at the Hamilton Mineral Separation Plant (MSP), including waste by-products and contaminated materials resulting from the processing and transport operations as follows:

o By-products from the processing of heavy mineral concentrate at the Hamilton MSP;

o used dust filter bags from the Hamilton MSP; and

o Other chemically inert material contaminated with naturally occurring radioactive material.

in accordance with the endorsed plans.

2.2 Commencement of the Permit

Condition 1 of the Permit states: This permit does not come into operation until:

a. Iluka has applied to the Department of Economic Development, Jobs, Transport and Resources to vary the 2003 Work Plan to identify a new endues utilisation of Pit 23 and to vary the rehabilitation plan; and

b. Iluka has applied to the Minister to surrender part of MIN 5367 (Pit 23); and

c. The Department of Economic Development, Jobs, Transport and Resources has approved the Work Plan Variation; and

d. The Minister has registered the partial surrender of MIN 5367.

The permit comes into operation on the same day the Work Plan Variation is approved, and the partial surrender of MIN 5367 is registered.

The Variation to the 2003 Douglas Mine Work Plan was approved on the 13th April 2017, and the partial surrender of MIN5367 was registered on 11th May 2017, this being the date of commencement of the Permit.

10

Per Section 13.2 of the EMP, the EMP and Rehabilitation Performance Reports will be subject to review by an independent auditor prior to submission to the Responsible Authority.

2.5 Rehabilitation and Vegetation Management Plan

Due to continued operations within Pit 23 no actions relevant to rehabilitation and vegetation management were undertaken in the H1 2020 reporting period.

3 Delivery and Disposal of Materials into Pit 23 No wastes were disposed into Pit 23 during the H1 2020 reporting period.

4 Monitoring Results 4.1 Groundwater

4.1.1 Bore network status The Pit 23 bore network includes several new monitoring bores installed in 2018 per the recommendations in the independent desktop review of proposed by-product disposal (EES, 2016). The augmented bore network therefore satisfies Condition 28(c) of the Permit. The status of Pit 23 monitoring bore network is given in Table 1. The blocked monitoring bore (BW36) has been decommissioned and replaced with a new monitoring bore (BW36A) which was installed in October 2019. Consistent with Section 7.6.3 the replacement bore (“BW36A”) was installed by a licensed driller pursuant to a ‘Licence to Construct Works’ (Works Licence WLE074849) issued by GWM Water. As per Condition 28(d) of the Permit, bore installation was supervised by qualified hydrogeologist. Bore locations are provided in Figure 3.

4.1.2 Standing water levels In accordance with Section 7.9.1 of the current endorsed EMP (Rev 4, July 2017) groundwater levels are measured on a monthly basis at bores WRK300 – WRK304 inclusive, GW01 to GW08 inclusive and BW36A and BW45B. All other bores (BW5, BW28A, BW53, IWB2 and IWB6) are measured on a biannual basis. Groundwater level hydrographs for these bores expressed in groundwater elevation (metres above Australian Height Datum, mAHD) are given in Table 2 and Figure 4 – Figure 6. Data includes that obtained during scheduled events and ad-hoc measurements. All bores along the predicted flow path (Figure 4) exhibit stable standing water levels in the preceding 24-month period and in comparison to long-term trends; bores up-gradient of Pit 23 (Figure 5) exhibit relatively stable water levels with minor fluctuation.

4.1.3 Groundwater quality

4.1.3.1 Ionic balance ratios Per Section 7.9.2 of the current endorsed EMP (Revision 4, July 2017) chloride:sulfate (CL:SO4) and sodium:calcium (Na:Ca) ratios in groundwater are assessed from results obtained during scheduled and/or follow-up groundwater sampling events. Per the EMP, a consecutive reduction in either ratio of >10% applies as a potential indicator of seepage from Pit 23 having arrived in a bore and is a trigger for further investigation. Per the EMP, further investigation would include:

• comparing the timing of the consecutive >10% reduction in ionic ratios with the hydrogeological model predictions;

• comparing the timing of the ionic balance trigger with other analytes (e.g. radionuclides, heavy metals) to identify any corresponding exceedances in those analytes in the same rounds of sampling;

• where such a correlation exists completing a detailed investigation of cause and impact, including possible reviews of hydrogeological or solute transport models.

Calculated Cl:SO4 and Na:Ca for the reporting period are given in Table 3. As above, this includes ratios as determined from the results of scheduled and follow-up sampling. Reductions of >10% in one or both ratios in consecutive and/or follow-up sampling events occurred on one (1) occasion in the reporting period in a bore (GW01) down-gradient to Pit 23: As detailed further in Section 4.1.3.3, the ionic balance trigger corresponded with an elevated Selenium result, however, this result is below the precautionary limit based on background values which have naturally elevated concentrations at GW01 and are above the standard SEPP WoV objectives. These observations are not considered to be associated with Pit 23.

Repeated ratio

exceedance? NOTES

• Calculated ratios in green represent values that increase following an initial “>10%” reduction (i.e. no consecutive >10% reduction)

• Calculated ratios in red represent values above the “>10%” reduction threshold (initial identified exceedance). • Calculated ratios in red highlight represent a confirmed “>10%” reduction in consecutive or follow-up samples • I.D. = insufficient data to allow calculation of ionic ratio (only one data-point available) • GW04 has previously been incorrectly referenced as being down gradient of Pit 23. Groundwater modelling and particle

tracking per EMM (2019) indicate that GW04 is cross-gradient to the predicted groundwater flow path from Pit 23. • BW28A is incorrectly referenced in the EMP (Revision 4) as being down-gradient of Pit 23. Groundwater modelling and

particle tracking per CDM Smith (2014) and EMM (2019) indicate that BW28A is cross-gradient to the predicted groundwater flow path from Pit 23.

4.1.3.2 Radionuclide concentrations In accordance with Section 7.6.7 of the EMP, biannual groundwater samples obtained from the monitoring locations are subjected to in-field and laboratory analysis for a suite of target parameters, which includes target radionuclides (Thorium, Uranium, Radium-226, Radium-228 and Uranium- 238). Radionuclide concentrations determined during both scheduled and follow-up sampling are presented in Table 4. Ionic balance ratios are also shown to identify any potential correlation with seepage from Pit 23. In summary:

• several exceedances of the Uranium-238 (U-238) and Radium-228 (Ra-228) upper trigger levels were observed in the reporting period in several bores up-gradient and cross-gradient to Pit 23 (i.e. in bores not on the predicted flow path or which represent local background conditions);

• ionic balance ratios showed frequent fluctuation spatially and temporally, and between samples obtained over relatively short time periods, with no correlation to radionuclide concentrations. This suggests that the measured radionuclide concentrations and ‘exceedances’ are the product of natural variation, consistent with the findings of previous groundwater studies for the greater Douglas site (Jacobs 2014; CDM Smith 2014; EMM 2018).

The long-term trends in Ra-228 and U-238 concentrations verses ionic balance ratios are shown in Figure 7 – Figure 22. Consistent with the above summary, there is no evident correlation between elevated radionuclide concentrations and fluctuation or declining trends in Cl:SO4 or Na:Ca ratios. It is recognised that this ionic balance ratio ‘percentage-reduction’ approach to trigger the completion of a groundwater investigation in the current endorsed EMP (Rev 4, July 2017) was based on limited available baseline data at the time of EMP development. This method is thus conservative and overly sensitive to natural variation and is likely to result in ‘false flag’ exceedances, as demonstrated in the McGlashin Swamp Seepage Exceedances Assessment completed by EMM in the 2018 reporting period (EMM, 2018). That is, the current approach does not consider trend-based change in groundwater chemistry that accounts for seasonality or other influences on groundwater chemistry over a sufficient period of time. Revised site-specific trigger levels for groundwater quality, developed using the now expanded monitoring dataset and applying a trend-based trigger approach across all target analytes per the ANZECC/ARCMANZ (2000) guidelines, will therefore be implemented in the next revision of the EMP (Revision 5).

• I.D. = insufficient data to allow calculation of ionic ratio (only one data-point available) • Groundwater arrival year is based on groundwater model predictions (particle tracking) per CDM Smith (2015) and EMM (2019), and assumes that groundwater flow originates from Pit 23 immediately on commencement of the first by-product disposal to into Pit 23 (December 2011).

• GW04 is incorrectly referenced in the EMP (Revision 4) as being down gradient of Pit 23. Groundwater modelling and particle tracking per EMM (2019) indicate that GW04 is cross-gradient to the predicted groundwater flow path from Pit 23.

• BW28A is incorrectly referenced in the EMP (Revision 4) as being down-gradient of Pit 23. Groundwater modelling and particle tracking per CDM Smith (2014) and EMM (2019) indicate that BW28A is cross-gradient to the predicted groundwater flow path from Pit 23.

4.1.3.3 Other analytes In accordance with Section 7.6.7 of the EMP, biannual groundwater samples obtained from the monitoring locations are subjected to in-field and laboratory analysis for a suite of target parameters. Analyte concentrations above trigger limits that coincided with ionic balance ratio triggers are presented in Table 5 & Table 6 and Figure 23. In summary:

• sampling detected an elevated selenium result at GW01 during February as part of the follow up sampling required due to an ionic balance trigger that occurred during January’s scheduled sampling;

• sufficient data is available to determine background concentrations for GW01, which is determined as the 75th percentile value based on the mean and standard deviation of the available data. For GW01, the 75th percentile (background) value is higher than the standard SEPP WoV objectives and therefore applies as the upper trigger (background value); and

• all results are consistent with historical values and do not indicate seepage from Pit 23.

All groundwater quality monitoring data (laboratory and field data) for the reporting period for all parameters monitored is provided in Appendix B and Appendix C of this report, respectively.

4.2 Surface water quality

4.2.1 Runoff-fed surface water sites In accordance with Section 8.7.1 of the EMP, surface water samples must be obtained from nominated runoff-fed surface water monitoring points if a discharge of run-off from the disturbed area of Pit 23 and surrounds occurs. No discharges occurred during the reporting period and subsequently no follow-up monitoring was required.

4.2.2 Groundwater-fed surface water sites In accordance with Section 8.7.2 of the EMP, quarterly surface water samples obtained from the nominated groundwater-fed surface water monitoring points down-gradient of Pit 23 (i.e. surface water features receiving groundwater base-flow) are analysed for a suite of target parameters to identify the potential expression of Pit 23 groundwater seepage.

Results obtained for specific parameters are summarised in sections 4.2.2.1 - 4.2.2.3 below. All surface water quality monitoring data for the reporting period and for all parameters monitored (laboratory and field results) is provided in Appendix D and Appendix E of this report.

4.2.2.1 Ionic balance ratios Assessment of potential Pit 23 seepage and expression into surface waters is based on an analysis of Cl:SO4 and Na:Ca ratios obtained from quarterly monitoring, with a consecutive reduction in either ratio of >10% applied as potential indicator of Pit 23 seepage and expression at surface.

Ionic ratio results for nominated surface water monitoring locations in the H1 2020 reporting period are given in Table 7. The data presented includes results preceding and following the H1 2020 reporting period to show longer-term trends and to demonstrate the influence of seasonality in both the availability of data (ability to obtain samples) and the influence that this natural variability has on surface water chemistry and hence the calculated ratios. The reliability of ratios calculated from data obtained after a long elapsed period of time (i.e. due to a lack of recent samples), and which suggest




32

a consecutive >10% ratio exceedance, thus need to be interpreted with caution as they are more likely to reflect natural variation than any influence of Pit 23 seepage. With reference to Table 7, no reductions of >10% exceedances in either one or both ratio’s occurred during the reporting period.

4.2.2.2 Radionuclide concentrations Section 7.9.1 of the EMP prescribes the locations for surface water monitoring and the monitoring frequency, as summarised in Table 8. These locations are subject to sampling and laboratory analysis for radionuclides (Thorium, Uranium, Radium-226, Radium-228 and Uranium-238). Radionuclide monitoring results for the reporting period are presented in Figure 24 and Figure 25. The corresponding monitoring data for radionuclides in surface water is provided in Appendix A. Note that for concentrations reported as below the laboratory limit of reporting / limit of detection (as indicated by “<”) the numerical value is treated as a negative concentration to enable graphical representation in order to demonstrate that sampling for that analyte was undertaken in compliance with the EMP. The monitoring results for radionuclides in surface water obtained during the reporting period confirm nil exceedances of any precautionary or upper trigger. Further, no off-site discharges from the confines of Pit 23 or immediate area occurred. Note that long-term data for these surface water points is available and the data presented in Figure 24 and Figure 25 represents all current data for these points.

4.2.2.3 Other analytes In accordance with Section 8.7.2 of the EMP, quarterly samples (if available) obtained from the monitoring locations are subjected to in-field and laboratory analysis for a suite of target parameters.

As discussed in Sections 4.2.1 and 4.2.2.1 there have been no runoff or discharges from site throughout the reporting period and no instances where ionic balance ratios were triggered at surface water monitoring locations that may be influenced from groundwater discharge.

4.3 Noise

In accordance with Section 10.1.4 of the endorsed EMP, noise level measurements will be undertaken in the unlikely event that noise complaints are received. No noise related complaints were received during the reporting period, and hence no noise levels measurements were undertaken.

4.4 PM10 concentrations in air In accordance with Sections 9.6 and 10.1.4 of the endorsed EMP, the concentration of PM10 dust in air at the Lyon’s and Chadwick’s residences is measured using high volume (‘hi-vol’) air samplers on a one-in-six day monitoring cycle. The location of these hi-vol air samplers relative to Pit 23 are shown in Figure 27. 12-month rolling results for PM10 compared to daily rainfall are shown in Figure 26. Results adhere to the expected year-on-year pattern of lower airborne PM10 concentrations in winter months.

4.5 Radiation monitoring – other

It is a requirement of the Iluka Radiation Management Licence 300042022 that works relating to the minerals sands by-product disposal into Pit 23 are conducted in accordance with a Radiation Management Plan (RMP) and a Radioactive Waste Management Plan (RWMP), including the monitoring programs under those plans, to ensure that radiation doses are below the prescribed limit. Radiation monitoring relevant to this performance report includes:

• Radon concentrations in air;

• Gross alpha activity concentration of airborne dust; and

• Radionuclide concentrations in groundwater and surface water. Results for radon concentrations in air and gross alpha activity concentration of airborne dust are detailed below. Results for radionuclides in groundwater and surface water are detailed in Sections 4.1.3.2 and 4.2.2.2, respectively.

4.5.1 Radon concentrations in air Monitoring of radon concentrations in air is undertaken at four locations within and immediately adjacent to Pit 23 and at two residences east of Pit 23 (Chadwick’s) and south of Pit 23 (Rises). Radon monitoring is undertaken using Landauer “Radtrak2” radon/thoron track etch detectors and the newer Rapidos High Sensitivity (“Rapidos HS”) radon detectors (Figure 30). The Rapidos HS detectors were implemented in Q4 2018 for side-by-side comparison with the existing Radtrak2 detectors, with initial results from the Rapidos HS detectors indicating that airborne radon levels are significantly lower than those indicated by the less sensitive Radtrak2 detectors, and therefore provide a more accurate measure of actual airborne radon levels in the vicinity of Pit 23 and at local residences. This side-by-side comparison will continue through 2020 to allow for meaningful statistical comparison of radon data between units over time. No high-sensitivity thoron detectors are available and thoron monitoring will continue using the Radtrack2 detectors. Radon and Thoron monitoring results for the reporting period are presented in Table 9 and Table 10, and also in Figure 29 and Figure 30. All measured radon and thoron levels in the H1 2020 reporting period were well below the reportable levels irrespective of the detectors used.

4.5.2 Gross alpha concentrations in airborne dust As noted in Section 4.4, sampling for airborne particulates in PM10 dust is conducted using high volume (hi-vol) air samplers located at the Chadwick’s, Lyons and Rises residences (see Figure 27). On a quarterly basis hi-vol units are run for a continuous 96 hour period for purposes of monitoring gross alpha concentration in air, which represents a total air sample volume of approximately 6,000 m3. The filters are weighed to determine the total dust loading in mg/m3 and then analysed for gross alpha activity expressed as millibequerels/m3 (mBq/m3). The results for the monitoring period are in line with historical values and are shown in Table 11 and Figure 31.

5 Management Actions 5.1 Monitoring bore audits

In accordance with Section 7.6.2 of the EMP, audits of the monitoring bore network are undertaken on monthly or bi-annually and outcomes reported annually within this EMP and Rehabilitation Performance Report. Bore integrity (e.g. physical condition, blocked/dry or poor yield) is assessed as part of the groundwater monitoring program. As per Section 4.1.1 of this report, all bores are in serviceable condition with the exception of BW36 which is blocked and was replaced with BW36A in October 2019.

5.2 Groundwater flow paths from Pit 23

In accordance with Section 7.9.1 of the EMP, groundwater levels measured at bores WRK300 – WRK304 inclusive, GW1 to GW7 inclusive, GW9, BW36A and BW45B are used to construct groundwater contours in the area of Pit 23 and surrounds and infer groundwater flow paths from Pit 23, with these levels and flow paths compared with the groundwater levels and flow paths predicted by the hydrogeological model. Groundwater level contours are provided in Figure 32 (EMM 2019; EMM 2020). This compares the 2019 modelled contours per EMM (2019), and interpreted groundwater contours as at June 2020 including standing water level data for new monitoring bores installed in 2018 and 2019. From these June 2020 contours it is confirmed that:

• groundwater contours and flow-paths are consistent with the 2019 modelled contours and prior year contours; and

• groundwater flow from Pit 23 is still to the north and north-west.

5.3 Groundwater model review and recalibration

Sections 7.10 and 8.7.2 of the endorsed EMP outlines the circumstances that will trigger a review and recalibration of the hydrogeological model.

An update of the Douglas Mine (inclusive Pit 23) hydrogeological model was commissioned through EMM Consulting in December 2018 in response to the potential groundwater seepage impacts identified during surface water monitoring at McGlashin’s Swamp in the 2017 reporting period. This also satisfied the commitment for a review of the model within two (2) years of the Planning Permit being granted.

Whilst complimentary seepage impact investigation (EMM, 2018) determined that the observed exceedances were associated with natural phenomena and un-related to Pit 23, a review and update of the groundwater model was required in accordance with the Pit 23 EMP.

Preliminary findings of the 2019 groundwater model update were presented to the Responsible Authority and Pit 23 Technical Reference Group (TRG) by Iluka and EMM Consulting personnel at a meeting held at the HRCC Council Chambers on 23rd May 2019. The final modelling report was completed and provided to the Responsible Authority in Q3 2019.

This modelling will be used to validate existing model predictions on the groundwater flow path and groundwater flow rates from the Pit 23 facility, and to inform updates to groundwater-related content with the next iteration of the Pit 23 Environmental Management Plan (EMP, Rev 5).

5.4 Maximum surface level of disposed materials in Pit 23

In accordance with Section 7.9.1 of the EMP, the maximum elevation of the upper surface of materials disposed of at the end of the reporting period must be reported. The Pit 23 void consists of an upper and lower disposal area; no wastes were disposed into Pit 23 during the H1 2020 reporting period. Accordingly, the survey undertaken on the 8th of December 2017 confirming the upper surface of materials deposited in Pit 23 (i.e. the elevation of capped material in the upper disposal area) remains unchanged at 193 mAHD.

5.5 Non-compliances

There were no non-compliances for the H1 2020 reporting period. 5.6 Comments and complaints received

No complaints or comments were received during the H1 2020 reporting period. 5.7 H1 2020 Completed Actions

There were no actions required to be completed during the reporting period. 5.8 H2 2020 Proposed Actions

The following actions are planned for H2 2020:

• submission of the updated Pit 23 Incoming Waste Monitoring Plan (IWMP) and Environmental Management Plan (EMP) as required by the default two-year review periods stipulated within these plans. The updated EMP will include outcomes of the updated groundwater modelling completed by EMM in 2019;




44

• annual review of the Pit 23 Risk Analysis and Response Plan (RARP) risk register as per Section 6 of the EMP; and

• Installation of groundwater monitoring bore GW04A to be located between GW04 and BW36A as previously agreed with Auditor.

5.9 Other matters

5.9.1 Annual geotechnical audit In accordance with Section 10.5.2 and 10.5.3 of the EMP, geotechnical audits are completed on an annual basis with the last audit completed in December 2019 (AMC Consultants, 2019). The next audit is scheduled for November 2020.

5.9.2 Pit 23 Risk Register annual review Per Section 6 of the EMP, the Pit 23 Risk Analysis and Response Plan (RARP) was developed by AECOM Australia Pty Ltd who recommended that the Pit 23 Risk Register (contained as Appendix A of the RARP) be reviewed annually at the time when EMP and Rehabilitation Performance Reports are developed. Reviews of the Pit 23 RARP risk register were conducted in December 2018 and presented in the prior 2018 EMP and Rehabilitation Performance Report submitted to the Responsible Authority on 3rd June 2019. A review of the Pit 23 RARP risk register was undertaken in April 2019 as part of the review and update of the Environmental Management Plan (EMP) and is scheduled to be reviewed in H2 2020.
